Abstract: PROBLEM TO BE SOLVED: To properly set a reception frequency in the case of receiving information about a limited area such as traffic information. SOLUTION: A current position is discriminated (step 101), a frequency at which area information of the discriminated current position is transmitted is discriminated based on information of a frequency list prepared in advance (steps 102, 103, 104), and whether or not the discriminated frequency differs from the frequency of the signal received at present (step 105). When different and the reception of the discriminated frequency is tried and received (steps 106, 107), the reception of the frequency is selected (step 110).

Title: Detection of abnormality in arc profiling
Inventor: SEKINO AKIYUKI
IPC: B23K9/12
Filed: 1984-04-20
Abstract: PURPOSE:To detect automatically welding abnormality in automatic profiling welding device by calculating the differences between the min. value and max. value of welding current separately in each weaving direction and deciding that profiling in welding is abnormal when either value of the differences is larger than the set value. CONSTITUTION:The min. value IL2 of the welding current in the back hand weaving period from the left to right of a welding torch 1 is detected after the current value IL1 at the left end is detected in the back hand weaving period. The min. value IR2 of the welding current in the forehand weaving period is detected after the current value IR1 at the right end is detected in the forehand weaving period. The differential current values (IL1-IL2) and (IR1-IR2) of the respective detected currents are detected during welding under weaving in the above-mentioned way. IL1 is large, IL2 is small or IR1 is large and IR2 is small when the work deviates from the normal position for the torch 1. Then the (IL1-IL2) or (IR1-IR2) attains the value larger than the normal differential current value K and the definite deviation of the work 2 in the horizontal direction is decided.

Title: Production of glass powder
Inventor: KURIHARA KOICHIRO
IPC: C03B8/00
Filed: 1995-04-06
Abstract: PURPOSE: To obtain a glass powder so as to enable the response to diversified small-quantity production at a low production cost by heat-treating a glass raw material powder mixed so as to afford a target composition at a temperature below the complete melting temperature. CONSTITUTION: Each raw material powder is weighed and mixed so as to provide a target composition in the method for producing a glass powder. The mixed powder is heat-treated at a temperature below the complete melting temperature for melting all the raw material powder to afford the objective glass powder. In the method for producing the glass powder, the heat-treating step corresponds to a melting and stirring step and a pulverizing step in a conventional process for producing the glass powder, the movement and diffusion of atoms among particles of the raw material powder are caused by heat- treating the raw material powder at the temperature below the complete melting temperature of the raw material powder to accelerate the vitrifying reaction and homogenization. Since the produced glass is in a powdery form, the pulverizing step is usually unrequired.  When the glass powder having a finer particle diameter is required, the pulverizing step is required. The sufficiently mixed raw material is required in order to sufficiently initiate the vitrifying reaction.

Title: Production of optical master disk
Inventor: ONO MASUMI
IPC: G11B7/26
Filed: 1994-04-20
Abstract: PURPOSE:To improve a recording density by providing the surface of a resist layer with a transmitted light limiting layer contg. a material to allow transmission of only the light having the intensity higher than the prescribed intensity, exposing this resist layer via this layer and enabling formation of extremely small phase pits beyond the limitation by lambda/NA. CONSTITUTION:The resist layer 2 is first formed on a transparent glass substrate 1 by applying a photoresist thereon by a spin coating method, etc., in order to produce an optical master disk. Saturable dyestuff is likewise applied by a spin coating method, etc., on the layer 2, by which the transmitted light limitation layer 3 is formed. The substrate 1 provided with these layers 2, 3 is exposed by using an optical recorder (cutting machine) using a laser beam 11. Namely, the laser beam L emitted from a laser beam source 11 is reflected by a mirror 12 and is made incident on an electro-optic modulator 13. The laser beam L modulated in the intensity is reflected by mirrors 15, 16 and is converged by passing an objective lens 14, by which a spot is generated on the layer 2. The substrate 1 is rotated and the lens 14 and the mirror 16 are moved in the diametral direction of the substrate 1 by a moving mechanism, by which the phase pits are concentrically or spirally formed.

Title: Waveform shaping circuit
Inventor: NAKAMURA NAOYUKI
IPC: H03K5/08
Filed: 1987-04-02
Abstract: PURPOSE:To prevent malfunction by turning on a transistor (TR) of emitter follower operation when a waveform is distorted to the input terminal of the titled circuit connected to a transmission line, and causing a current flow from the input terminal to the transmission line thereby shaping the waveform. CONSTITUTION:Assuming that a signal with a lower potential than a ground potential caused by the distortion in the waveform enters from an input terminal 1, then a TR 5 is turned on and a current flows from the emitter till the input terminal 1 reaches nearly the same potential as the ground potential. Thus, the energy causing distorted waveform is absorbed at the moment, and the waveform is shaped. Thus, an excellent waveform shaping characteristic is obtained to prevent malfunction of a logic circuit.

Abstract: PURPOSE:To hold a fixing and a pressure roller long in life by cutting the outer peripheries of both ends of a roller formed in an inverted crown shape and forming maximum diameter parts of the roller a specific inside from the end parts. CONSTITUTION:The pressure roller 40 is formed in the inverted crown shape having a minimum diameter part 41 at its center part in the lengthwise direction so as to prevent transfer paper P from being wrinkled at nip parts at the time of fixation. The outer peripheral parts in contacting parts with the transfer paper P at relatively low frequencies are cut by a specific quantity to form the maximum diameter parts 42 and 43 the specific distance inside from the end surfaces 44 and 45 of the pressure roller 40. Consequently, the wrinkle smoothing effect for the transfer paper is obtained and the angle of the maximum diameter part can be made obtuse; and the concentric pressing force to the roller of the other side by the maximum diameter part is reduced to become small and the durability of the other-side roller is improved.

At the time of autonomous travel, reaction time gamma, sense coefficient (b) and attention coefficient omega as parameters to decide how to keep the distance between cars are matched with the driving operation characteristic of a driver and based on the inter-car distance signal S1 and the self car speed signal S2, an automatic speed control means 12 executes control so as to keep the distance between the preceding car and the car itself constant. Thus, at the time of autonomous travel, the driver can obtain a driving feeling matched with the habit or the taste of the driver itself.
